| Question |
Answer |
| Omental Foramen boundary- anterior |
portal v., hepatic a., bile duct |
| Omental foramen boundary -posterior |
interior vena cava |
| Omenatl foramen boundary-superior |
caudate lobe of liver |
| omental foramen boundary-inferior |
superior aspect of 1st part of duodenum |
| Esophagus |
passes through esophageal hiatus in diaphragm at T10, joins stomach at T11 |
| Diaphragm |
around hiatus - forms physiological sphincter |
| physiological sphincter |
prevents gastroesophageal reflux |
| upper 1/3 |
under conscious control |
| middle 1/3 |
mixid |
| inferior 1/3 |
under autonomic control exclusively |
| vagus n. forms |
plexus on esophagus & passes w/it through esophageal hiatus into abdomen |
| L. gastric a. |
from celiac trunk |
| R. gastric a. |
from hepatic a. |
| R. gastro-omental |
from gastroduodenal |
| L. gastro-omental |
from splenic |
| Short gastric |
from splenic |
| Duodenum |
4 parts |
| part 1, Duodenum |
horizontal at L1 - peritonealized |
| part 2, Duodenum |
vertical from L1-L3, retroperitoneal, contains ampulla for bile/pancreatic duct |
| part 3, Duodenum |
horizontal at L3, retroperitoneal |
| part 4, Duodenum |
curves forward & becomes peritonealized at L2 |
| Jejunum & Ilium |
Peritonealized in "the mesentery" |
| Jejunum |
more vascular, more prominent vasa recta & more circular folds (plicae circulares for absorption) |
| Cecum & appendix |
intraperitoneal |
| ascending colon |
retroperitoneal |
| transverse colon |
intraperitoneal |
| descending colon |
retroperitoneal |
| sigmoid colon |
intraperitoneal |
| tenia coli |
longitudinal muscular bands |
| haustra |
pouch like sacculations |
| Celiac trunk level |
T12 |
| Celiac trunk branches |
L. gastric, splenic, common hepatic |
| Celiac trunk supplies |
esophagus, stomach, spleen, liver, gallbladder, part of duodenum, part of pancreas |
| Superior Mesenteric A. level |
L1 |
| Superior Mesenteric A. branches |
jejunal, ileal, ileocolic, r. colic, middle colic |
| Superior Mesenteric A. supplies |
uncinate process of pancreas, jejunum, ilium, cecum, appendix, ascending colon, most of transverse colon |
| Inferior Mesenteric A. level |
L3 |
| Inferior Mesenteric A. branches |
L. colic, sigmoid, superior rectal |
| Inferior Mesenter A. supplies |
distal end of transverse colon, descending colon, sigmoid colon, rectum |
| Inferior Mesenteric V. drains into |
splenic v. |
| Splenic & superior mesenteric vv. join to form |
hepatic portal v. |
| L. gastric v. drains into |
portal v. |
| Sympathetics-Celiac trunk |
Greater splanchnic n. T5-T9 |
| Sympathetics-Superior Mesenteric A. |
Lesser splanchnic n. T10-T11 |
| Sympathetics-Inferior Mesenteric A. |
Lumbar Splanchnic nn. L1-L2 |
| Parasympathetics blood leaving aorta above L2 |
Vagus n. |
| Parasympathetics-blood leaving aorta below L2 |
Pelvic splanchnic nn. (S2-S4) |
| Spleen |
on L. side opposite ribs 9-11 |
| Spleen supported by |
phrenicocolic ligament |
| Spleen rupture causes |
severe intraperitoneal hemorrhage |
| Major site of stress-induced immune suppresssion |
spleen |
| Spleen becomes enlarged with |
monnucleosis & portal hypertension |
| Pancreas |
retroperitoneal except tip of tail |
| Pancreas forms |
bed of stomach posterior to omental bursa |
| main pancreatic duct joins |
common bile duct, accessory duct is present sometimes |
| abdominal impact |
results in rupture against verterbral column |
| duct damage |
results in auto-digestion |
| Pancreatitis |
results from blockage of ducts (gallstones), excessive alcohol consumption, medications |
| Liver #___ Lobes |
4 |
| Lobes of liver |
right, left, caudate, quadrate |
| Liver recieves blood from |
hepatic artery & portal v. |
| Liver drains into |
inferior vena cava |
| Liver toxicity |
alcohol, acetominophen, antifreeze |
| Liver disease |
cirrhosis |
| Liver - a lot of matastases because |
organs which drain through poral vein |
| R. & L. hepatic ducts join to |
form common hepatic duct |
| Common hepatic duct joins cystic duct to form |
common bile duct |
| cystic duct has |
spiral configuration - serves as valve |
| Gallbladder |
in costal margin at midclavicular line |
| Gallstones |
block duct causing pain (following high lipid meal) |
| Gallbladder innervation |
celiac plexus - receive sensory afferents from R. Phrenic n. perceived in C3-C5 dermatomes |
| Esophageal & azygos vv. |
esophageal varices |
| Superior & inferiro rectal vv. |
hemorrhoids |
| paraumbilical vv. to anterior abdominal wall |
caput medusae |
